Magnetic Tape Subsystems

This document outlines the features and benefits of the TA78 and TA81 magnetic tape subsystems within a VAXcluster environment. The TA78 is presented as the high-performance option, while the TA81 offers an economical, midrange alternative. Both units function as shared resources via HSC50 or HSC70 servers, utilizing Digital Storage Architecture (DSA) to reduce I/O overhead on host CPUs. Key highlights include improved data reliability through error correction, increased system availability, and support for high-speed local backup. The document also details configuration parameters, upgrade paths, and technical specifications for both models.
